    Significance and Use

    4.1 This practice may be used to evaluate pertinent characteristics of washable T-shirts.

    4.2 T-shirts may be subject to extra processes such as garment dyeing, garment washing, printing, application of embroidery or trims. An individual process or combination or processes may affect the performance of the final product.

    4.3 This practice may be used by mutual agreement between the purchaser and the supplier to establish purchasing specifications.

    1. Scope

    1.1 This practice covers test methods and procedures used to evaluate important characteristics of machine washable T-shirts. T-shirts may be made of knitted fabric composed of any textile fiber(s) or blend of fibers and intended to be used as underwear or as an outer garment.

    1.2 T-shirts' characteristics may be assessed either as a final product or at any intermediate processing stage.

    1.3 This practice excludes T-shirts intended for hand washing or dry cleaning care.
